What To Drink After Surgery    

If you're wondering what to drink after surgery, here's a list of "Best" and "Acceptable" Fluid Choices.

Your Fluid Goal : 64oz of calorie free fluids daily

What to Drink After Surgery:

These are the purest and best choices because they DON'T contain artificial sweeteners:

  • Water: cold, room temperature, or warm
  • Alkaline Water (“pH water”)
  • “Fruit Infused Water”/ “Spa Water:” water + added slices of lemon, cucumber, lime, orange, etc.
  • Water + True Lemon, True Lime, True Orange or True Grapefruit
  • Herbal tea (Chamomile, Mint, etc.) or decaffeinated tea
  • Broth, Bouillon (Chicken, Vegetable)
  • Hint Water 

What to Drink After Surgery :            ACCEPTABLE CHOICES

These Choices CONTAIN Artificial Sweeteners

Note: Just about everything will taste too sweet after surgery. Use more water or add crushed ice to dilute these to your taste preference:

  • Propel
  • Crystal Light
  • Powerade Zero, Gatorade Zero
  • Vitamin Water Zero
  • Bai
  • Water + sugar free flavoring like Mio, Dasani, or a generic brand (Use 2-3x as much water as directed) 

Note: Coffee does NOT count as a hydrating fluid. Sorry ☹


Did you know that 1 can of soda has 40grams of sugar?! That’s 10 teaspoons!

Don’t drink your calories.


  • Soda
  • Sugar tea
  • Fruit Juice
  • Lemonade
  • Kool Aid
  • Gatorade
  • Powerade  

Now That You Know What to Drink After Surgery, Here’s
How to Do It

Knowing what, and how much to drink is one thing…

 …doing it is another.

In beginning it may be challenging to drink enough. It’s easy to get dehydrated FAST if you don’t stay on top of your fluids.

I always suggest following a “fluid schedule.” Something like this:

  • 6am - 10am: 16 oz
  • 10am - 2pm: 16 oz
  • 2pm - 6pm:   16 oz
  • 6pm - 10pm: 16 oz

It works best to use small bottles or cups and finish them frequently rather than having one very large jug that you have to work your way through.

16oz x 4 times per day = 64oz!

I find this type of schedule works like a charm with my patients.

You can adjust the times based on your personal schedule.

Possible Barriers to Drinking Fluid

“Water Tastes Funny/Different Than It Used To”

What to Do:  Try a different brand of bottled water, they all taste different. If you drink tap water, add a filter. Try alkaline water. Try a beverage other than water, like tea or broth. 

 “My Beverages Taste Too Sweet”

What to Do: Drink beverages that do NOT contain artificial sweeteners. OR, use smaller amount of Crystal Light, flavor drops, etc. to flavor your water. OR, simply dilute your beverages with water or ice.

 “It Hurts to Drink”

What to Do:  Change the temperature of your beverage. Room temperature water or warm water with lemon or warm broth or hot herbal tea may be easier to drink than cold water. 

Note: If you’ve gotten dehydrated it may be hard to drink. Make sure you’re drinking at least 64oz every day.
